specific Embodiment approach
[0034] Install four trimming discs on the adjusting arm, the sum of the diameters of the four trimming discs is equal to or slightly smaller than the radius of the grinding pad, and the four trimming discs are arranged linearly on the adjusting arm, so that when the adjusting arm When pointed at the center of the pad, the four conditioning discs completely cover one radius of the pad.
[0035] The four trimming discs are driven and connected to the four rotating drive mechanisms one by one, and the rotating drive mechanism can use a motor, so that each motor drives a trimming disc to rotate, and the four trimming discs are driven by four motors, and each motor is designed By setting different rotation parameters, each dressing disc can be driven to rotate with different rotation parameters.
[0036]The four trimming discs are driven and connected to the four gas pressurizing mechanisms one by one. The gas pressurizing mechanism can use pneumatic diaphragms. In this way, each p...
